Abstract
The disclosure relates to a threaded member having an annular groove which is of greater depth than the base of the adjacent thread. A resilient ring is mounted in the groove having an outer periphery extending above the base of the thread and a plurality of projections are formed at spaced locations around the ring to be deformed by the engagement of the threaded member with a corresponding threaded member to form a seal between the respective threads of the engaging members.
